I found it while perusing Toys R Us the other day for someone else's child, and it looks like it would have cleared up at least one of our problems -- what to do with that pain in the you-know-what potty seat.

We had a tendency of putting it in the bathtub when it wasn't in use because there was simply no other place to put it.

But this hook hangs off the toilet tank and makes use of some currently unusable space. At $3.99, even if it doesn't work, at least you're not wasting big bucks.
